Currently ICMIZER 2 allows using FGS model with depth 1 through 6.
With FGS 2 it looks 2 hands ahead, with FGS 1 it looks only 1 hand ahead, so it is faster.
The recommended depth setting is number of players at the table minus one, making it FGS2 for 3 players, FGS 3 for 4 players, FGS4 for 5 players. For more players not all FGS depths are available. The recommended setting is at least FGS2 for situations with more than 5 players.
