This is the style of this player. He had a very comfortable stack and for me that is the reason he was calling, especially in the first hand, although the fact he had nothing. I am sure with less chips he would fold the first one. The re-raise on the flop I think if it was a bigger with top pair, he could fold.
About the second hand, that guy, who flops a set can not play so slowly on the flop with 4 players. If I was on the place to the guy with the deuces, of course I will call 998 chips, when I have straight draw with 6 outs. The second hand - the player with the pocket fives must bet on the flop with the set. This hand shows that playing strong
hands slowly sometimes is a very bad idea.
