3-4-3 is generally regarded the second strongest formation in Hattrick, second only to 3-5-2.
Examples of 3-4-3 line-ups
|1CD, 3 IM, 1WTM|
This is one of the most used formations by scoring trainers. It gives a strong midfield by having 3 midfielders and usually a fouth one played as Winger Toward Middle. It also gives a very strong central attack by using 3 forwards. Variations of this formation can be made by playing the wingbacks defensive, switching the side from where the extra forward is promoted and playing the midfielders offensive or defensive. Some even play the central defender offensive for the extra bonus in midfield.
|1CD, 2 IM, 2W.O|
This is a rare played 3-4-3 formula. The middle is not so strong unless you use some very skilled midfielders. The attack is very good if you use this formation, especially if the midfielders are played offensive.
Tactics for Scoring Trainers
As a scoring trainer, you'll find that your tactics are rather limited, as you need to strengthen your midfield while playing three forwards. The most common formation using 3 forwards is the 3-4-3 with three inner midfielders and a winger, either played offensive or winger towards middle. The most common variations of the 3-4-3 are:
|E.FO||IMO||IMD||WTM or OW|
|E.CD||IMO||IMO||WTM or OW|
The first formation gives you decent wing defence, which is useful against winger trainers, people playing forward toward wing or anybody that has a decent wing attack (unless you're trying to guess the side you'll opponent will play his wing). It's a good "all round" formation.
The second formation works well against most teams who concentrate on central attack (other scoring trainers, notably), but it leaves you relatively weak in wing defense. If the use of tactics like AIM and AOW is worth its drawbacks it's still open for discussion.
General tips Before each game examine your oppostion, and if it's got strong midfield, but weak attack, consider playing with an OCD or with CA (if you have the proper defenders, of course; CA can be especially lethal with the 4-3-3 and 5-3-2 formations). If its attack is strong, play your inner mids defensive, and if its defence is strong, play your inner mids offensive. Generally speaking, try to find the opponent's weak spot and hit there. If the opponent has no wing defence, use a FTW or an offensive winger. If you're simply superior to your opponent in something and he can do nothing about it, insist on it and think what your opponent might do to counter your advantage. For example, if you have a better midfield than your opponent, consider that he might play counter attack, so strengthen either your back-line or your attack.
