ivey, benyamine etc buying in for 16k?

[chirpy]

Sometimes will see them sit at 200/400 nl/plo with 40k but often ivey will sit with 16k? Anyone have any strategical insight as to why this may be? Presumably theyre not conceding that they are at a skill disadvantage (and thereby needing to shortstack to profit) and bankroll is evidently no problem so this strategy seems peculiar?

Anyone have any ideas as to why they may do this, particularly when they are used to playing bigger games live and known for wanting to gamble - Would seem logical that Ivey would want the games online to play as big as possible, yet often buys in short?
