Now this is a move you’ll see a lot when playing tournaments. It’s no coincedence it’s used a lot, because this move has a certain strength (if your stack is still large enough). It’s power is twofold: it can force your opponent to fold his (better) hand right there ánd if you get called you can beat your opponent by making your draw.

This play is perfectly demonstrated by the great Eli Elezra during an episode of Poker After Dark (S02E45). Watch it yourself (first hand):

So Eli flops the nut flushdraw and basically has only two moves left after Allan Cunningham’s continuation bet and Ivey’s raise: going all-in or fold. Now he choses the first option because there was an extra factor involved here: the fact that Phil Ivey was playing fairly aggressive during this tournament. Eli observed this correctly and in that way (with Ivey not even having toppair for example) it would be easier for Ivey to lay down his hand.
